D. C. COOK UNIT 1 CYCLE 29 Revision 0 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the following subsections. These limits have been developed using the NRC-approved methodologies specified in Technical Specifications 5.6.5.

2.1 SAFETY LIMITS 2.1.1 Reactor Core Safety Limits (Specification 2.1.1)

In Modes 1 and 2, the combination of thermal power, pressurizer pressure, and the highest loop average temperature (Tavg) shall not exceed the limits as shown in Figure 6 for 4 loop operation.

2.2 REACTNITY CONTROL 2.2.1 SHUTDOWN MARGIN (SDM) (Specification 3.1.1)

Shutdown margin shall be greater than or equal to 1.3% Af(/lc for T avg > 200°F Shutdown margin shall be greater than or equal to 1.0% Af(/lc for Tavg ~ 200°F 2.2.2 Moderator Temperature Coefficient (MTC) (Specification 3.1.3)

The BOL/ARO-MTC shall be less positive or equal to the value given in Figure 1.

The EOL/ARO/RTP-MTC shall be less negative or equal to --4.54E-4 Ak/k/°F.

This limit is based on a Tavg program with HFP vessel Tavg of 569.0 to 573.0 °F.

Where: ARO stands for All Rods Out BOL stands for Beginning ofCycle Life EOL stands for End of Cycle Life RTP stands for Rated Thermal ,Power HFP stands for Hot Full ThermaLPower Page 3 of 23

D. C. COOK UNIT 1 CYCLE 29 Revision 0

b. The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less negative or equal to

-3.84E-4 Ak/k/°F at a HFP vessel Tavg of 569.0 to 573.0 °F.

c. The Revised Predicted near-EOL 300 ppm MTC shall be calculated using Figure 7 and the following algorithm:

Revised Predicted MTC = Predicted MTC + AFD Correction + Predicted Correction*

  • Predicted Correction is -0.30E-4 Ak/k/°F.

If the Revised Predicted MTC is less negative than the SR 3.1.3.2 limit (COLR 2.2.2.b) and all of the benchmark data contained in the surveillance procedure are met, then a MTC measurement in accordance with SR 3 .1.3 .2 is not required.

d. The MTC Surveillance limit is:

The 60 ppm/ARO/RTP-MTC should be less negative or equal to

-4.41E-4 Ak/k/°F at aHFP vessel Tavg of 569.0 to 573.0 °F 2.2.3 Shutdown Bank Insertion Limits (Specification 3.1.5)

The shutdown rods shall be withdrawn to at least 228 steps.

2.2.4 Control Bank Insertion Limits (Specifications 3 .1.6)

a. The control rod banks shall be limited in physical insertion as shown in Figure 2.
b. Successive Control Banks shall overlap by 100 steps. The sequence for Control Bank withdrawal shall be Control Bank A, Control Bank B, Control Bank C and Control Bank D.

2.3 POWER DISTRIBUTION LIMITS 2.3.1 AXIAL,FLUX DIFFERENCE (AFD) (Specification 3.2.3)

a. The Allowable Operation Limits are provided in Figure 3.
b. The AFD target band is +/-5% for a cycle average accumulated burnup
o.o MWD/MTU, but may be reduced to +/-3%.

  • K(Z) for P~0.5 THERMAL POWER Where: p = RATED THERMAL POWER .
a. CFQ=2.09
b. K(Z) is provided in Figure 4.
c. FQc(Z) is the measured hot channel factor including a 3% manufacturing tolerance uncertainty and a 5% measurement uncertainty..
d. W(Z) is provided in either Table 1 for the +/-5% AFD target band or in Table 2 for the +/-3% AFD target band.
e. FQw (Z)=FQc(Z) x W(Z)x Fp The W(z) values are generated assuming that they will be used for a full power surveillance. When a part power surveillance is performed, the W(z) values should be multiplied by the factor 1/P, when P is> 0.5. When P is :'.S 0.5, the W(z) values should be multiplied by the factor 1/(0.5), or 2.0. This is consistent with the adjustment in the FQ(z) limit at part power conditions.
f. For Cycle 29, FP = 1.02 for all bumups associated with Note 2a of SR 3.2.1.2.

When no penalty is required, FP = 1.00.

The boron concentration of all filled portions of the Reactor Coolant System, the refueling canal and the refueling cavity shall be greater than or equal to 2400 ppm++.

+ These are Safety Analysis values. With readability allowance, the corresponding values are 578.2°F for Tavg , and 2200 psig for Pressurizer Pressure.

++ This concentration bounds the condition of l<eff :S 0.95 which includes a 1% Afdk conservative allowance for uncertainties. The boron concentration of 2400 ppm includes a 50 ppm conservative allowance for uncertainties.
